This book was released on 1974 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: The article is devoted to the questions of deformation (strain) and stressed state of an ice cover with a allowance for the time of load influence. They analyze the available experimental data and the existing mathematical concepts; they discuss the results from theoretical and experimental studies; developed more rigorous relationships of load effect; and reviewed the acutal engineering problems originating during the employment of an ice cover as a construction-assembly area, for winter crossings and as main transportation lines.

Download or read book An Ice Thickness tensile Stress Relationship for Load bearing Ice written by Philip R. Johnson and published by . This book was released on 1980 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The bearing capacity of a floating ice sheet is of considerable interest. The pattern of ice thickness vs tensile stress for a fixed load and fixed ice properties was examined and showed some constant relationships. It proved possible to completely describe the ice thickness-tensile stress pattern in terms of a single number. When the load was changed by increasing the payload but not altering the geometry of the load pattern, other relationships were found that described the tensile stress in the ice sheet for any combination of payload and ice thickness. This provides a simple method of finding tensile stress in the ice that can be used in the field.

Book excerpt: The problem investigated in this thesis is the prediction of the deflection and stresses in a floating ice sheet under loads which act over a long period of time. This problem is currently important for oil exploration offshore in the Arctic. A review of analytical methods for predicting the bearing capacity of an ice sheet is given. The problem is formulated by assuming the ice is isotropic with a constant Poisson's ratio. The shear modulus is assumed to obey a linear viscoelastic model. The specific model selected is a series of one Maxwell model and two Voigt models. One of the Voigt models has a negative spring constant which produces tertiary creep. The ice model exhibits a primary, secondary, and tertiary creep response, similar to that observed in uniaxial creep tests of ice. The material properties in the viscoelastic model may be a function of the vertical position in the ice sheet, but all these material properties must be proportional to the same function of position. Using the thin-plate theory for the floating ice sheet, the solution is obtained for the deflection and stresses in the ice sheet for primary, secondary, and tertiary creep regions. It is then shown that for a load that is not distributed over a large area, the time-dependent part of the deflection and stresses is relatively independent of the load's distribution. For the elastic case, the stress significantly depends upon the load's distribution. Results are given for the deflection and stresses as a function of time and distance from the load. The maximum deflection and stresses occur at the center of the load. At this point the deflection increases with time, while the stresses decrease; i.e., the stresses relax. (Author).

Download or read book Sea ice Bearing Strength in Antarctica written by J. E. Dykins and published by . This book was released on 1969 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: To update the operating criteria for C-121, C-124, C-130, C-141, and C-5 aircraft in the Antarctic, the bearing capacity of the McMurdo annual sea-ice sheet was analyzed for short-term loading. The load curves developed by elastic theory predict the ice thickness required as related to the changing strength characteristic of the ice sheet associated with the seasonal warming trend. These load curves provide operating criteria that are more related to the ice-sheet temperature than the operating criteria now in use. This analysis is only an interim solution in the development of aircraft operating criteria; continued research is needed to provide a better understanding of the ice-sheet response to both short- and long-term loads. The load curves and instructions presented in Appendix B are recommended to replace the present operating criteria appearing in NCEL Technical Note N-888, 'Interim Aircraft Load Curves for Sea-Ice Runways at McMurdo, Antarctica.'

Book excerpt: This report considers a floating ice sheet supporting a crowd of people who are free to assume any distribution. The problem is analyzed when the people gather into a long strip, two strips, or a circular area, all of which may vary in size. The worst possible size is determined for the safe bearing capacity in each case. Upon comparison of the results, a single equation is suggested for practical use. (Author).
